“The longevity ecosystem has a specific habit of conflating mechanistic plausibility with demonstrated human benefit,” says Ali Hashemi, cofounder and CEO of Metabolic Health. “A compound that improves a biomarker in mice, extends lifespan in yeast or alters a cellular pathway in vitro does not translate to a meaningful human health outcome.”
It’s a distinction that much of the internet’s wellness economy depends on people not understanding. “The history of medicine is a graveyard of interventions that looked brilliant mechanistically and failed catastrophically in human clinical trials,” he adds, “The longevity supplement market is running about 10 years ahead of the science”.
The more a certain “miracle supplement” infiltrates the zeitgeist, the more consumers are spending hundreds a month chasing benefits that may never materialise outside a laboratory setting.
Social media amplifies the problem because certainty, overall, performs better than nuance. Nobody builds a viral personal brand by saying the evidence is preliminary and further research is needed. A 2025 study in JAMA Network Open analysed nearly 1,000 posts about popular medical tests across Instagram and TikTok and found that 87% promoted benefits while fewer than 15% mentioned any downsides – with the accounts behind them commanding a combined 194 million followers. The infrastructure of misinformation is now as sophisticated and well capitalised as any legitimate industry. It is, in fact, an industry. So after all the hype, what actually deserves attention?
Hashemi’s first response is to challenge the question itself. “A universal supplement stack is not real medicine. Real medicine begins with objective diagnostics, not protocols built around population trends.” In other words, before buying supplements, get tested. The most evidence-based protocol is not a protocol at all – it’s a blood panel. That said, the epidemiological data does reveal several recurring deficiencies across the Gulf.
Vitamin D
“Vitamin D is the most urgent,” says Hashemi. “Despite living in one of the sunniest regions on earth, deficiency and insufficiency rates here track between 60 and 80% of the population across published regional data. Extreme summer heat drives an indoor lifestyle – cars to offices to malls with very little meaningful UV exposure. Cultural clothing patterns limit skin exposure, and higher skin pigmentation requires significantly more UV exposure to synthesise adequate vitamin D.”
